Most doors have six sides. The Bible is concerned with just two: the inside and the outside. God’s Son said, “I am the door. By Me if any man enters in he will be saved” (John 10:9). The Lord Jesus is not one of many doors to heaven—He is the only door to heaven.
It was a Thursday night, in Houston, Texas. The Whataburger restaurant was open 24 hours a day. At this time of night, though, all the doors were locked and only the drive-through window remained open for customers. Jon Marx, the manager, wanted a smoking break. As the manager, Jon was the only one with the keys to unlock the doors. When he stepped through the back door of the restaurant the door automatically locked behind him. Outside the restaurant the back was dimly lit, but Jon had been out there many times before in the dark; he knew his way around. A few minutes later the two employees still inside the restaurant heard gunshots. They went to check on the manager, but they could not find him. They tried calling him on their headsets, but he did not answer. They could not get outside because the doors were locked and only the manager’s keys could open them. They contacted the police, but before the police could get there, a customer pulled into the parking lot and found Jon slumped against the back door — dead. If you had been at the Whataburger, which side of the back door would you have wanted to be on? The inside or the outside? Jon was on the WRONG side of the door!
Being on the wrong side of the door cost Jon his life, but if you are on the wrong side of heaven’s door it will cost you infinitely more — your soul. God wants you inside because there is danger on the outside of salvation’s door. Jesus said, “In that place (on the outside) there shall be weeping and gnashing of teeth” (Luke 13:28). In Luke 16, the Lord Jesus told of a man who exited this world and went out into eternity on the wrong side of the door and he’s still there today. What is it like? The all-knowing Lord Jesus says it is a place of torment, flames, separation from God, and unanswered prayer. We can therefore understand God’s profound concern for your salvation. The Lord Jesus strongly urged His hearers, “Strive to enter at the strait gate” (Luke 13:24). He wants you to make every effort to be on the inside of the door. He wants you to be forever with Him. God guarantees eternal safety on the inside of heaven’s door. God longs for you to enjoy the safety, the peace, the love, the joy, and the satisfaction found only on the inside of the door.
While heaven’s door stands wide open now, it is going to close soon. The Master of the house is going to stand up and shut the door. When God closes the door those on the inside will be eternally shut in and those on the outside will be eternally shut out. What God shuts, no one can open — not for a second. God doesn’t want you to be shut out. He wants you to make this a priority. He wants you to be eternally with Him. Remember the words of the Lord Jesus, “I am the door. By Me if any man enters in he shall be saved.”
